When an unplanned stop occurs due to power supply interruptions, only the high-speed train equipped with on-board energy storage system (OESS) can be self-propelled. In this case, a rational operating strategy is required to ensure passengers’ safety and transportation efficiency. In this paper, an operation strategy for high-speed trains under emergency self-propel with limited energy and power is presented to improve the success rate of train emergency self-propel. Firstly, a train emergency self-propel power model with the output power characteristics of OESS is proposed, and the power flow during emergency traction sourced from the energy storage device is described. Then, a dynamic planning algorithm considering the output power constrains of on-board energy storage devices is designed. And a multi-stage optimal control problem is built to realize the global optimization of the train operation. Finally, to verify the effectiveness and practicality of proposed strategy, simulation cases are conducted. The results show that the operation method generates feasible operation strategies with lower energy consumption under ensuring the safety of passengers' safety, and improves the efficiency in train emergency self-propel.
